ROLLER-BLIND SUPPORT FOR CASEMENT WINDOWS.

Application filed December 22, 1925. Serial No. 77,081.

Our invention relates to improvements in roller blind supports forcasement windows, and the object of the invention is to devise a rollerblind support for casement or French windows which will not interferewith any of the ordinary fixtures, which Wlll enable the blind to hangclose to the glass, in which the support for the draperies extendingboth in front of and at the back of the blind will be provided for, andin which the lock of the casement window will not be interfered with,and it consists essentially of the arrangement and construction of partsas hereinafter more particularly described.

Fig. 1 is a perspective view of the casement window showing our deviceapplied thereto.

Fig. 2 is a sectional plan view through Figure 1 showing our device infull.

Fig. 3 is an enlarged transverse sectional view through our roller blindsupport showing the roller blind by dotted lines.

Fig. 4 is a plan sectional detail through the adjustable portions of ourroller blind support and showing the means for locking the parts in theadjusted position.

Fig. 5 is a sectional view through our support on line 5-5, Figure 2.

In the drawings like characters of reference indicate correspondingparts in each figure.

1 is a bracket which is hingedly mounted at 2 to the frame of thecasement window; a bracket 1 being provided at each side of such frame.3 arearms extending horizontally from the bracket and preferably formedof sheet metal having the edges rolled inward as indicated at 4 and v5to form a guideway.

6 is an extension which is also formed of sheet metal and is providedwith corresponding rolled edges 7 and 8 which fit within the rollededges 4 and 5 so that the part 6 is slidable longitudinally with thepart 3. The outer ends of the portions 6 are provided with dependingsupporting members 9 from each of which extends a rubber bumper member10 adapted to engage the sash 11 of the casement window adjacent itsfree edge.

12 and 13 are brackets provided with upwardly extending tongue portions12 and 13 14 is a curtain hanger of the usual type formed of two memberstelescopically engaging one with the other as indicated at 15, the endsof the hanger being provided with slots 16 into which the tongues 12 and13* enter so as to support the curtain hanger in place.

17 is a back curtain hanger which is supported at its ends on thebracket member 1 and supporting members 9. The back ourtain hangers mayalso be divided into two portions telescopically connected together asindicated at 18.

19 is a lock washer oval in form, the major diameter being slightlylarger than the width between the sides of the extension 6, the minordiameter being less than such width. The washer 19 is provided with acentral transverse slot 20.

By turning the washer 19 into position shown in Figure 4 the sides ofthe portions 6 are slightly spread so as to frictionally engage thesides 4 and 5 of the arms 3 and thereby prevent the longitudinalmovement of the extension 6 within the guides formed by the sides 4 and5.

When it is desired to adjust the roller blind support so as to fit anydesired width of window, the washer 19 is turned to a position at rightangles to the position shown thereby freeing the extension 6 andpermitting it to slide to the desired position so as to either extendthe width of the support or shorten it.

The portions 9 are provided with slotted openings 9 and 9 and thebracket 1 is provided in its opposing face with correspond ingpositioned recesses 1 and 1 into which the usual supporting pintles ofthe roller blind 20 extend.

In setting up our device the members 3 and 6 of the support are adjustedto the required position and the hinge 2 secured to the frame of theeasement window. The roller blind of a corresponding width required forthe window is then inserted in the usual manner in either orifices 1, 9or 1", 9 according to how close it is desired to place the blind to theWindow.

It will thus be seen that when the blind is mounted as above describedit may be swung outward free or independently of the casement windowsash so that it will not interfere in any way either with the sash orits fixtures, and at the same time our device forms a support for theinner and outer curtains which are swung outward with the blind support.

From this description it will be seen that we'vhave devised a Verysimpledevice adapted for supporting roller blinds in front of a casementwindow so that it will be swung independently thereof and yet held.clear of the window so that it will not interfere in any way with itssecuring lock or other fixtures and which may be readily adjusted to anywidth of sash and securely locked in its adjusted position.

What we claim as our invention is:

The combination with a Window frame, of

bracket formed integral with the outer end of the other extensiblemember and between which and the first mentioned bracket a shade rolleris adapted to be mounted, an

extensible curtain-support, and means for detachably connecting saidcurtain support either to the inner or outer face of the aforesaidbrackets.
